The CAN-CBX-Pt100 is designed for the direct connection of up to four temperature sensors. Simple resistance measurements can also be performed. Pt- and Ni-resistance sensors are supported. The sensor resistors can be connected in two- or four-wire configuration. The conversion of the four sensor resistor inputs is realized by four independent ΣΔ-converters. Linearisation according to NIST is achieved by the on board microcontroller.
The CAN interface is designed according to ISO11898-2 high-speed layer with electrical isolation and supports bit rates up to 1 Mbit/s. The CANopen-node number and the CAN bit rate can be easily set via coding switches. Four LEDs indicate the module and CANopen node status.
The power supply and the CAN bus signals can be supplied via the InRailBus connector (TBUS connector) integrated in the mounting rail. In this way, a minimum of cabling of the individual modules is achieved. All esd CBX modules are compatible with each other and can be plugged onto the bus as required. It is also possible to disconnect individual modules from the InRailBus without interrupting the bus signals or the power supply.
The module comes with CANopen firmware according to CiA 301and supports the CiA 404 profile for measuring devices.
